DEPRECATED

This repository has been deprecated in favor of the native support for StepFunctions definitions in YAML.

AWS StepFunctions YAML Macro

Use YAML to define your Amazon States Language for your AWS CloudFormation-defined StepFunctions state machines

Made with ❤️ by Trek10. Available on the AWS Serverless Application Repository

Usage

After deploying this into your account, you can use the SFNYAML transform:

Transform: [ AWS::Serverless-2016-10-31, SFNYAML ]

Then you can replace the JSON-defined DefinitionString with YAML-defined DefinitionString Amazon States Language:

  MyStateMachine:
    Type: AWS::StepFunctions::StateMachine
    Properties:
      RoleArn: !GetAtt ExecutionRole.Arn
      # DefinitionString: !Sub |
      #   {
      #     "StartAt": "Hello"
      #     "States": {
      #       "Hello": {
      #         "Type": "Task",
      #         "Resource": "${Function.Arn}",
      #         "End": true
      #       }
      #     }
      #   }
      DefinitionString:
        StartAt: Hello
        States:
          Hello:
            Type: Task
            Resource: !GetAtt Function.Arn
            End: true

All of the CloudFormation intrinsic functions are supported, and used as expected

Known Issues

• Does not support AWS::NoValue being used in the definition
